SAS EuroBonus - Star Alliance award advice NRT-CPN-LHR?

Dear FT'ers,
I've got a buisness class award travelling from NRT-LHR.
I'm trying to narrow down my choices but am having a hard time.
Please, could someone help me with a recommendation or two?
I'm looking at:
ANA on their 747,
or make a connection for an Asiana(747) or SAS(340) flight,
or go really crazy and fly to BKK just so I could do one leg on SQ, and the other on TG with a 12 hr layover?
I flew SK on an MD-88 from LHR-GOT and found the service was outstanding, (for short haul! Well it was 2001) and was interested to see SK was an option here.
Thanks for the look.
Cheers,
Kendall

Since this same note was posted in 4 other forums, I'll close it here. Separately I agree with SEA_Tigger's advice and also wonder whether you've found award space already on the various routes you identify? In any case you won't go wrong with NH's new business class on this route, and the non-stop is compelling.

Regards,
Gary
